Description
Technical field
It the utility model is related to automatic control technology field, and in particular to the wireless telecommunications system between a kind of control device
System.
Background technology
PLC and DCS is common control device, it is necessary to which multiple control devices are mutual in many complicated control systems
Linkage, it is therefore desirable to the transmission of signal can be carried out between control device.
In the prior art, multiple control devices in control system are connected using cable, such as optical fiber, but such cost
It is higher.By taking optical-fibre communications as an example, calculated according to 5 PLC, it is necessary to which the dedicated photoelectric converter of intermediate arrangement 5, cost are
More than 100000 yuan, 200,000 yuan of optical fiber slip ring, 800 meters of 2,000,000 yuan of composite cables, cost is huge.In addition, it is also required to when installing optical fiber
Produce many human costs.
In view of this, it is special to propose the utility model.
Utility model content
The purpose of this utility model is to provide the wireless telecommunication system between a kind of control device.
To achieve these goals, the basic technical scheme that the utility model uses is as follows：
Wireless telecommunication system between control device, including multiple control devices, the signal end connection of each control device
There is antenna, connected between each control device by antenna communication.
Alternatively and preferably, the multiple control device includes a central control equipment and around the central control equipment
The periphery control device of setting, the antenna are omnidirectional antenna.Distance is not far between such system architecture is suitable for control device
Or the unfixed situation of relative position.
Alternatively and preferably, the multiple control device includes the control device that relative direction is fixed, and relative direction is solid
The signal end of fixed control device is all connected with directional aerial.Relative direction is true between such system architecture is suitable for control device
It is fixed, but apart from situation uncertain or farther out.
Further, the control device is PLC controller or DCS controllers.
Wireless telecommunication system between control device provided by the utility model, does not use traditional optical fiber connection control
Each controller in system, but the signal end in each control device connects antenna, by antenna transmission signal, realizes nothing
Line communicates, and so saves purchase and installs the cost that optical cable produces.In mobile control device also without dismantling connection line
Cable, saves working time and human cost.
Brief description of the drawings
Fig. 1 is the structure chart for the wireless telecommunication system that the utility model embodiment one provides；
Fig. 2 is the structure chart for the wireless telecommunication system that the utility model embodiment two provides.
Embodiment
Some illustrative embodiments for being shown in below with reference to the accompanying drawings describe the principle of the present invention and spirit.Should
Understand, describe these embodiments just for the sake of better understood when those skilled in the art and then realize the present invention,
And not limit the scope of the invention in any way.
The utility model embodiment provides a kind of wireless telecommunication system of control device.Include multiple controls in the system
Control equipment, the relative position between these control devices may fix, it is also possible to be not fixed, but needed between control device into
Row communicates to realize coordinated signals.The basic conception of the present embodiment is the signal end connection antenna in each control device, so
It can be connected between each control device by antenna communication.During signal transmission, it is no longer necessary to cable, so can be with
Save and make a big purchase the costs such as cable, photoelectric converter in large quantities, it is also more convenient in mobile control device, it is not necessary to dismantle cable.
Embodiment according to the present utility model, control device can be that PCL controllers can also DCS controllers.
Antenna can use omnidirectional antenna or directional aerial.360 ° of all uniform spokes are shown as in omnidirectional antenna horizontal direction
Penetrate, it is non-directional, the wave beam of one fixed width is shown as in vertical direction, and lobe width is smaller under normal circumstances, and gain is got over
Greatly.Omnidirectional antenna is suitable for relative position and the unfixed situation use of relative direction between control device, but preferably respectively sets
The distance between standby not too long (such as 100 meters or so), because omniantenna, the covering surface of propagation is still propagated greatly
Apart from a bit weaker.Directional aerial transmitting and to receive electromagnetic wave especially strong on some or certain several specific directions, and at it
It is then zero or minimum to launch on his direction and receive electromagnetic wave, therefore it is relatively solid suitable for multiple control devices to include direction
The situation (equipment being such as moved through on rail) of fixed control device, the direction between control device is fixed at this time, still
Distance can be not fixed, and even farther out (as far as several kilometers, closely to tens meters), in this case using directional aerial, be propagated
More efficient, effect is more preferable.
Embodiment one
The present embodiment provides the wireless telecommunication system between a kind of control device, including multiple control devices, the present embodiment
For PLC controller, the signal end of PLC controller is connected with omnidirectional antenna, and one of control device 1 is located at center, as in
Heart control device, other controllers 2 are periphery control device, are dispersed in around central control equipment.Each control device it
Between communicated by omnidirectional antenna.Wherein central control equipment can be used as master control equipment, for being set as other controls
Standby communication relay coordinates the work of other control devices.
Embodiment two
The present embodiment provides the wireless communication system between a kind of control device, including multiple directions each other are relatively-stationary
Control device, wherein control device 3,4 are located at side, and control device 5 is located at the phase of opposite side, control device 5 and control device 3
Direction is fixed, the relative direction of control device 5 and control device 4 is also fixed.Control device in the present embodiment controls for PLC
Device.The signal end connection directional aerial of these control devices, for directive sending and receives electromagnetic wave.At this time between control device
Direction determine that but can not known apart from length, control can also be adjusted flexibly in inventor under conditions of direction is not changed
Position between control equipment.
Real-time communication of the utility model by wireless communication applications between control device (such as PLC controller), it is significantly simple
On-site cable arrangement is changed, has reduced high conversion equipment expense, needed to need answering for optical fiber in high-tension cable in part
Close in cable, save optical fiber, greatly reduce cable expense.Feed cable is only needed to can be achieved logical in real time between equipment
News, interlocked control can be solved using wireless telecommunications.
Specific case used herein elaborates utility model design, and the explanation of above example is
It is used to help understand the core concept of the utility model.It should be pointed out that for those skilled in the art,
